  The Google search engine was used to carry out an accurate qualitative assessment of information available on NPS in a sample of 104 websites.
  
  
  RESULTS
  The monitoring has led to the identification of 14 NPS including herbal, synthetic, pharmaceutical and combination drugs that have been sold online.
